Metasedimentary rock successions in Sierra Albarrana Group (SW Iberia Autochthonous Domain) were deposited during the Early Paleozoic influenced by evolution of a peri-Gondwanan active margin. Their geochemical composition indicates dominant contributions from felsic igneous sources and an upper continental crust provenance. The high mineralogical maturity, together with negative ?Nd(530), rang...

In this paper, we present results of tectonic and geophysical investigations in the Kenya Rift valley, Nakuru area. We compiled a detailed geological map area based on published earlier works, well data satellite imagery. The was then integrated with original fieldwork cross sections were constructed. key areas, performed survey using Electrical Resistivity Tomography (ERT), Hybrid Source Audio...

Kimberlites occur as dykes up to 3 m thick and isometric bodies in the southern explored part of a NE-SW trending Karoo graben across the Mozambique Belt in northern Mozambique. The kimberlites are reported along four NW-SE-trending zones, and one ENE-WSW-trending zone. The kimberlites are macrocrystic hypabyssal Group Ia kimberlites based on their mineralogy and whole rock geochemistry. The ki...

The 3.22-3.10 Ga old Moodies Group, uppermost unit of the Swaziland Supergroup in the Barberton Greenstone Belt (BGB), is the oldest exposed, well-preserved quartz-rich sedimentary sequence on earth. It is preserved in structurally separate blocks in a heavily deformed fold-and-thrust belt. North of the Inyoka Fault, Moodies strata reach up to 3700 m in thickness. Detailed mapping, correlation ...
